[0014] A method for using a laser measurement assembly for engineering surveying and mapping comprises the following steps: Step 1: When surveying indoor projects, the handheld detection module and the power module are combined to enable the laser module to emit a detection laser that penetrates the optical lens. This allows for accurate and rapid distance measurement of indoor building dimensions, and data is recorded and integrated after multi-point measurement. Step 2: When surveying indoor curved walls, find a horizontal surface indoors and flip the two adjustment arms out of the storage slots. The two adjustment arms and the reference frustum provide stable support for the detection and power modules. Then, based on the flatness of the surface and using a spirit level, adjust the flipping of the two adjustment arms to achieve horizontal adjustment of the detection and power modules. Step 3: After the adjustment is completed, the driving motor drives the driving prism shaft to rotate. At this time, the driving prism shaft controls the damping rotating block and the telescopic guide slot to rotate. When controlling the rotation of the bevel gear, the transmission bevel gear plate and several teeth are rotated. The teeth are controlled by the gear ring. Since the rotating disk is plugged into the gear ring through several synchronous plug-ins, the synchronous plug-ins cannot be separated from the synchronous slots during normal driving rotation. At this time, the gear ring and the rotating disk rotate simultaneously, realizing the rotation control of the protective cover, and then realizing the laser module in the protective cover to measure the single reference point and multiple measurement points of the curved wall in front; Step 4: When the control bevel gear controls the protective cover to rotate continuously, the optical lens of the protective cover moves to the position of the control slot and abuts against the cleaning disk. At this time, the outer boss of the protective cover abuts against the constraint abutment block and cannot rotate. Then, when the transmission bevel gear plate controls the gear ring to rotate, the rotating disk cannot rotate. If the control bevel gear and the damping rotary block continue to rotate, the synchronous plug-in block will reciprocate and insert into several synchronous slots under the elastic telescopic support of the synchronous spring, but will not affect the normal rotation of the gear ring, the transmission bevel gear plate and the damping rotary block. At this time, the damping rotary block will control the cleaning disk to rotate continuously through the cooperation of the key bar and the key slot. The cleaning disk can clean the surface of the optical lens of the protective cover and cover it when not in use.

[0015] Compared with the prior art, the present invention has the following beneficial effects: This device sets a rotatable adjustment detection component in the detection combination module. When performing multi-point detection on indoor curved walls, it cooperates with the horizontal adjustment component carried by the power combination module to first adjust the horizontal conditions of the detection combination module and the power combination module. Then, the rotating adjustment detection component is used to perform multi-point reference detection on the same horizontal plane on the front curved wall. The device can be divided into two modes: handheld operation and stable placement operation. The support platform requirement is low during placement detection, which facilitates efficient use of indoor surveying and mapping. In addition, the maintenance processing component can wipe and maintain the optical lens for detection of light transmittance, making operation worry-free and convenient.

The maintenance processing component includes a cleaning disc 14, one side of the cleaning disc 14 is movably plugged into the damping rotary block 10, and the cleaning disc 14 is placed in the control groove 8. A movable support rod 12 is horizontally provided at the center of one side of the cleaning disc 14, and a telescopic guide slot 13 is provided in the damping rotary block 10. One side of the movable support rod 12 movably passes through the control bevel gear 23 and is plugged into the telescopic guide slot 13. The movable support rod 12 is plugged into the telescopic guide slot 13 and is provided with an anti-falling block.

Under the cooperation of the key bar 17 and the key slot 16, the cleaning disc 14 will be controlled to rotate continuously. At this time, the protective cover shell 5 cannot rotate, that is, the rotating disc 25 cannot rotate, and the control bevel gear 23 controls the transmission bevel gear disc 24 to drive the rotation of the gear ring 26, which will cause the synchronous plug-in block 29 to reciprocate and insert or disengage from the synchronous slot 28, which will not affect the normal rotation of the cleaning disc 14 and the telescopic guide slot 13.

[0025] A method for using a laser measurement assembly for engineering surveying and mapping comprises the following steps: Step 1: When surveying indoor projects, the handheld detection module 1 and the power module 2 are combined to enable the laser module 6 to emit a detection laser that penetrates the optical lens 7, which can accurately and quickly measure the distance of indoor building dimensions. After multi-point measurement, the data is recorded and integrated; Step 2: When surveying an indoor curved wall, find any horizontal surface in the room and flip the two adjustment arms 34 out of the storage slots 32. The two adjustment arms 34 and the reference frustum 31 provide stable support for the detection assembly module 1 and the power assembly module 2. Then, based on the flatness of the surface and using a spirit level, adjust the flipping of the two adjustment arms 34 to achieve horizontal adjustment of the detection assembly module 1 and the power assembly module 2. Step 3: After the adjustment is completed, the driving motor drives the driving prism shaft 22 to rotate. At this time, the driving prism shaft 22 controls the damping rotary block 10 and the telescopic guide slot 13 to rotate. When the bevel gear 23 is controlled to rotate, the transmission bevel gear plate 24 and a plurality of teeth are rotated, and the teeth are controlled to rotate the gear ring 26. Since the rotating disk 25 is plugged into the gear ring 26 through a plurality of synchronous plug-ins 29, the synchronous plug-ins 29 cannot be separated from the synchronous slots 28 during normal drive rotation. At this time, the gear ring 26 and the rotating disk 25 rotate simultaneously to realize the rotation control of the protective cover 5, and then realize the laser module 6 in the protective cover 5 to measure the single reference point and multiple measurement points of the front curved wall, or the handheld device is abutted against the vertical wall. After the detection combination module 1 and the power combination module 2 are adjusted horizontally, they remain stationary to perform the rotation measurement of the protective cover 5. Step 4: When the control bevel gear 23 controls the protective cover shell 5 to rotate continuously, the optical lens 7 of the protective cover shell 5 moves to the position of the control slot 8 and abuts against the cleaning disk 14. At this time, the outer boss of the protective cover shell 5 abuts against the constraint abutment block 11 and cannot rotate. Then, when the transmission bevel gear disk 24 controls the gear ring 26 to rotate, the rotating disk 25 cannot rotate. If the control bevel gear 23 and the damping rotary block 10 continue to rotate, the synchronous plug-in block 29 will reciprocately insert into several synchronous slots 28 under the elastic and telescopic support of the synchronous spring 30, but will not affect the normal rotation of the gear ring 26, the transmission bevel gear disk 24 and the damping rotary block 10. At this time, the damping rotary block 10 will control the cleaning disk 14 to rotate continuously through the cooperation of the key bar 17 and the key slot 16. The cleaning disk 14 can clean the surface of the optical lens 7 of the protective cover shell 5 and cover it when not in use.

A reset spring (15) is sleeved on one side of the movable support rod (12) outside the telescopic guide groove (13). A plurality of key slots (16) are provided on the movable support rod (12). A plurality of key strips (17) are provided on one side where the telescopic guide groove (13) sleeves the movable support rod (12). The plurality of key strips (17) are movably inserted into the plurality of key slots (16) respectively.

9. The laser measurement assembly for engineering surveying and mapping according to claim 8, characterized in that: A restraining abutment block (11) is provided on one side of the self-rotating movable groove (4) close to the control groove (8). When the optical lens (7) of the protective cover (5) corresponds to the cleaning disk (14), one side of the outer boss of the protective cover (5) abuts against the restraining abutment block (11), and the end surface of the cleaning disk (14) contacts the optical lens (7).

10. A method for using the laser measurement assembly for engineering surveying according to any one of claims 1 to 9, characterized in that: The following steps are involved: Step 1: When surveying indoor projects, the handheld detection combination module (1) and the power combination module (2) are combined to enable the laser module (6) to emit a detection laser that penetrates the optical lens (7), thereby accurately and quickly measuring the distance of indoor building dimensions, and recording and integrating data after multi-point measurement; Step 2: When mapping an indoor curved wall, find any horizontal surface in the room, flip the two adjustment arms (34) out of the storage slot (32), and the two adjustment arms (34) and the reference frustum (31) stably support the detection combination module (1) and the power combination module (2). Then, according to the flatness of the table surface, use the level bubble to adjust the flipping of the two adjustment arms (34) to achieve the horizontal adjustment of the detection combination module (1) and the power combination module (2); Step 3: After the adjustment is completed, the driving motor drives the driving prism shaft (22) to rotate. At this time, the driving prism shaft (22) controls the damping rotating block (10) and the telescopic guide groove (13) to rotate. When the bevel gear (23) is controlled to rotate, the transmission bevel gear disc (24) and a plurality of toggling teeth are rotated. The toggling teeth control the gear ring (26) to rotate. Since the rotating disc (25) is plugged into the gear ring (26) through a plurality of synchronous plug-ins (29), during normal driving rotation, the synchronous plug-in block (29) cannot be separated from the synchronous slot (28). At this time, the gear ring (26) and the rotating disc (25) rotate simultaneously, realizing the rotation control of the protective cover (5), thereby realizing the measurement of the single reference point and multiple measurement points of the front curved wall by the laser module (6) in the protective cover (5); Step 4: When the control bevel gear (23) controls the protective cover (5) to rotate continuously, the optical lens (7) of the protective cover (5) moves to the position of the control groove (8) and contacts the cleaning disk (14). At this time, the outer boss of the protective cover (5) contacts the constraint contact block (11) and cannot rotate. Then, when the transmission bevel gear disk (24) controls the gear ring (26) to rotate, the rotating disk (25) cannot rotate. If the control bevel gear (23) and the damping rotating block (10) continue to rotate, the synchronous plug block (29) Under the elastic and telescopic support of the synchronization spring (30), several synchronization slots (28) will be reciprocated, but it will not affect the normal rotation of the gear ring (26), the transmission bevel gear disk (24) and the damping rotary block (10). At this time, the damping rotary block (10) will control the cleaning disk (14) to rotate continuously through the cooperation of the key bar (17) and the key slot (16). The cleaning disk (14) can clean the surface of the optical lens (7) of the protective cover (5) and cover it when not in use.
